TipLap style tool sharpener

[Paul Jones]

Sorry about hijacking older dan's posting but thank you Toolmaker51 for the references to the Hardinge website.

I do mainly lathe machining for 1" or smaller diameter rod materials and like 5C and ER32 collets because of the thru hole holding for longer stock and higher accuracy than my 3-jaw chucks (these are not run true chucks). The 5C collets for hex, square stock and some rectangular stock extends the possibilities of what can be held very accurately in the lathe. If I had a 6-jaw run true chuck, I think this would be my main holding device the rod and hex stock except for the 3/8" or less diameters. The little ER16 collet chuck I made for my Unimat lathe has now become the go-to chuck for this small 3" swing lathe because of its accuracy. R8 collets are great for the milling machine but buy the best you can afford with the least TIR in order to extend milling cutter life. Good quality carbide milling cutters are expensive and the longer the cutter tool life the better.

Thank you for the discussion.
